While in his teens, Donny fathered a son, Todd, and raised him as a single parent up until Todd's 18th birthday. Now, after not seeing each other for years, Todd's world comes crashing down when Donny resurfaces just before Todd's wedding.

Todd: You were basically the worst parent ever!
Donny: I was awesome!
Todd: You let me eat cake and lollipops for breakfast every day!
Donny: That's what you asked for!
Todd: You're supposed to say no!
Todd: I didn't know what I was doing! I was 13,14 years old!
Todd: You know, what I remember is ME having to drive YOU home from the beach that time, because you were too drunk!
Donny: Somebody else's dad would have had another guy drive home!
Todd: I was eight!
Donny: And you drove like a fucking champ too.

Todd: That's because I got it in third grade, my body grew!
Dante Spirou: Vanilla Ice banged grandma? That's fucking awesome!
Donny: Facebook? You know I can't afford that shit. What am I, a billionaire?
Donny: Do you have any AXE body spray?
Todd: No, Donny. I don't have any AXE body spray. Because I'm not a fucking douchebag.
Donny: Since when it's become a douchebag thing?
Todd: [after punching Chad] At ease, bitch!

Donny, Todd: [gives him a gift]
Todd: You got me a gift... an earring? But I don't have a pierced ear.
Donny: Yeah...
Donny, Todd: [Donny jams the earring on his son's ear]
Todd: [his face smeared with blood] Am I bleeding?
Donny: I don't think so.

Jamie: OH MY GOD! I just found my wedding dress covered in barf! And something else...
Donny, Jamie: [inspects the dress]
